To all whom it ma? concern;

Be it known that I, JA s RCArrwrLL,

forming .a part of proper, "so as to provide for lateralmove ment of the coupler independently of the yoke. p

The invention is fully hereinafter de scribed, and is illustrated in the accompany- -igure 1 is a detail plan view ofthe center sills of a car, and showing a simple form of draft gear, and the coupler and yoke as being provided with-the improved connecting means; Fig.2 is a sectional view on the line 22 of-F1g.' 1, the sills and draft lugs being omitted; Fig. 3 is a detail side elevation of the butt of the coupler shank and the forward end of the yoke; 'Fi 4 is a sectional detail, on an e'nlarged'sca e, of the same parts, taken on the line 2-2 of Fig. 1; Fig. 5 is a detail plan of the'butt of the coupler shank, and showing the element constituting the connection between the shank and the yoke; Fig. 6 is a detail plan of the butt of the coupler shank; Fig. 7 is a detail plan section, on the line 77 of Fig. 4; Fig. 8 is a view in perspective of the element for connecting'the coupler with the yoke.

The forward ends of a pair of center sills ate a yoke, of the conventional M. C. B. type, inclosing the gear and having the for- 1 Specification of Letters Patent.- Application filed June 12, 1908.. Serial no. 488,014.

' ward" ends of its longitudinal arms lipped inwardly, as'shown at n, g, in accordance with the usual ractice.

The coupler is shown at f, and is provided tured, as shown at h, the forward and rearward walls of the aperture being curved, preferably being arcs of a circle struck from the vertical axis of the aperture. The side walls of the aperture h converge from each n end, forming the apexes k midway of the length of the aperture. A strut or bridge, w, extends horizontally across the aperture 12., mldway of its length and height. A pivot member, 6, is'located within the aperture h, and is secured b means of rivets, r, to the yoke e. The bo y portion of the pivot member is oblong in cross section, its front and rear walls bearing against the curved walls curvature; its side walls being. flattened and bearing against the apexes k. The pivot element is transversely apertured to loosely receive the strut or bridge. To permit of theassembling of the parts, the. pivot element is horizontally divided into two sections, the parting being through its strutreceiving aperture. The ends of the pivot element are provided with enlarged heads, I, 0, adapted to fit against the inner faces of the yoke arms and presenting forward faces,

the yoke lips, n, g. The inner end of the coupler shank bears a ainst the forward follower c,- and prefera ly is extended upwardly and downwardl to increase its bearing area, as most plain y shown in Fig. 3.

' I claim as my invention- In a draft mechanism for cars, in combination, a coupler bar having its butt vertically apertured, the front and rear walls of the aperture being curved and its side walls converging from front and rear; a yoke having top and bottom members inclosing the coupler butt; a two part pivot having its sections attached to the yoke members and entering the coupler bar aperture, the inner ends of the pivot sections being in cessedi the side walls of the pivot being flatof. the aperture 11. and conformmg thereto inm, p, which rest against the inner faces of.

abutting engagement and transversely re-- with any suitable form of head, g. The butt of the coupler shank f is vertically aper-v tened and engaging the apexes of the side walls of the aperture, and its front and rear walls bein curved and engaging and being of lesswi ththan the curved walls of the aperture and a bridge crossing the coupler bar aperture and passing loosely through the recesses in the pivot sections.

In witness whereof, I hereunto subscribe my name this 10th day of June A.-D., 1908;

JAMES R. GARDWELL.
